Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .060in MLS Cylinder Head Gasket - 4.350in Bore - LHS

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed specifically for the GM L18 Vortec 8100 Gen-VII Big Block V8 engine, offering a 4.350-inch bore and a compressed thickness of 0.060 inches. This gasket is for the left-hand side (LHS) of the engine. It's built to handle the demands of high-output engines, making it a solid choice for rebuilding or repairing these powerful V8s.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This advanced coating is designed to perform in tough sealing environments and works well with both aluminum and cast iron blocks, even when paired with aluminum heads. The center layer is uncoated stainless steel and can be varied to meet different thickness needs, ensuring a precise fit.

This Cometic MLS head gasket is a popular choice for a range of vehicles including the Chevrolet Suburban 2500, GMC Sierra 2500 HD, and Chevrolet Avalanche 2500. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation. Just make sure you're installing the correct side (LHS) for your application.
